上传照片在服务器中不起作用

代码在本地主机（examplep）中运行良好，这是我的网页的编辑部分。但当我把照片放在服务器上时，上传照片的功能不起作用（不将图像上传到服务器）。任何帮助都将不胜感激。下面是我上传照片的代码。

define ("MAX_SIZE","1000"); 
 $errors=0;
$image=$_FILES['image']['name'];
if ($image == "")
{
    $uploadmsg = '<br /><font color=red>'.ERR_BLANK_IMAGE_FIELD.'</font>';
    $errors=1;
}
if ($image) 
{
    $filename = stripslashes($_FILES['image']['name']);
    $extension = base_getExtension($filename);
    $extension = strtolower($extension);
    if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif")) 
    {
        $uploadmsg = '<br /><font color=red>'.ERR_UNKNOW_IMAGE_EXTENTION.'</font>';
        $errors=1;
    }
    else
    {
         $size=filesize($_FILES['image']['tmp_name']);
        if ($size > MAX_SIZE*1024)
        {
            $uploadmsg = '<br /><font color=red>'.ERR_EXCEEDED_SIZE.'</font>';
            $errors=1;
        }
        $newname="images/eitem_".$itemPart.".".$extension;
        if($photo != "images/eitem_item_default.png")
        {
            $delete = unlink($photo);
        }
        else
        {
            $delete=1;
        }
        $copied = copy($_FILES['image']['tmp_name'], $newname);
        if (!$copied || !$delete) 
        {                   
            $uploadmsg = '<br /><font color=red>'.ERR_IMAGE_UPLOAD_UNSUCCESS.'</font>';
            $errors=1;  
        }
    }
     if(isset($_POST['save']) && !$errors) 
     {
        $uploadmsg = "<br /><font color=red>".MSG_IMAGE_UPLOAD_SUCCESS."</font>";                   
        eitem_editItemPhoto($cid,$newname);                 
        eitem_editItem($cid,$itemPart,$shortDesc,$longDesc,$categoryList,$brandList,$packDetails,$minOrder,$supplier,$price);
     }
}
else
{
    eitem_editItem($cid,$itemPart,$shortDesc,$longDesc,$categoryList,$brandList,$packDetails,$minOrder,$supplier,$price);
} 

HTML

<div class="cell bottomBorder" style="width:170px; height:170px;vertical-align:middle; text-align:center;padding:5px;">
    <img src="../eitem/<?php echo $photo; ?>" id="imge_path" style="height:150px; width:120px"/>
</div>
<div class="cell bottomBorder" style="vertical-align:middle;">
    <input type="file" name="image" id="image">
    <div>(150px x 120px)</div>
        <?php echo $uploadmsg; ?><br />
        <span class="note">Please use an image with .png,.jpg or .gif file format.</span>
    </div>
</div>

编辑
当我试图在服务器中回显值时，我无法在$copied = copy($_FILES['image']['tmp_name'], $newname);行中获得$copied的值。但它在我的本地主机中工作
